By carefully brushing alcohol (fine art brush) with alcohol, the mould can be removed. </div><div>As to the corals, if they’re skeletal then the process you describe should be OK. But if they’re dried with their polyps intact then the alcohol would affect the pigmentation.</div><div><br></div><div>Hope that this helps.</div><div><br><div apple-content-edited="true">
